I was looking at Milzat's mod's and saw his wheel chocks. Thought I would give my modifications this type of chocks. When I built my first ones over 3 yrs ago I used 1/2" all thread bolt, which worked fine until I forgot to remove after hitching up trailer. They resembled the letter "S" instead of being straight. I drilled out the holes in the blocks and used a 3/4" (18" long) all thread. Then I welded 3/8" rod to the top to make a tee handle. I used a 2" flat washer and welded a 3/4" nut to it. Drilled 1/8" holes across the edge of the washer and wood screwed it to the lower wood block. A couple of inches down from the tee handle I welded a washer and nut on to the all thread. Now no wrench is needed to tighten or loosen the chocks. And the 3/4" thread withstands a "mistake" (I tested it again.... not intensionally).

I made a set a couple weeks back using treated 4X4 and 1/2" all thread. Thus far they have worked like a champ, and cost about 8 bucks to make. Beats the heck out of the 50 or so they'll charge you for the metal ones, and work just as well.

Funny story, my father in law and his brother made those about 15 years ago, same material as yours Steve. They were some miffed after using them for a few years to see a set manufactured and retailed that were exactly the same, albeit in metal or plastic. Moral of the story, if you have a good idea, patent the sucker.

83 sweet sweet days camped in 2008 - not easy in my neck of the woods!

I used treated 4X4. and an 18" piece of 1/2 inch all thread. I cut each Piece at 15 degrees on my miter saw. The wide portion is 5 1/2 inches. I drilled holes dead down the middle inserted the all thread, used a 1" washer and put nust on each end. I have seen designs with additional nuts, but I find it uneccessary because the tires dont move.

Mine are very similar to the sketch RAC has. The angle and length of the blocks are unique to each camper. I could not use the original set I made for my old TT, the dimensions were all wrong.

The first set I made for my 5er were still a bit to short. I made a mistake similar to bigbud450 and moved the camper with the chocks still engaged. The 1/2" all-thread folded like an "S". It was a PITA to remove. This set of chocks were still a bit too short. If tightened to much, they were a real pain to remove.

Made a new set that is approximately 1" longer and they work perfect. I painted them a bright red to help "remind me" to remove them before I take off.
